However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

Cylindrical heating chamber provides excellent radial temperature uniformity. Type text as it appears:: Linearized analog output permits connection to a strip chart recorder or datalogging instrument. Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator.

Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. Furnace cover has ports for flask exterior thermocouples, and a borosilicate glass thermocouple tube is provided to assure correct positioning of the gas temperature thermocouple inside the test flask. Modified crucible furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications.

The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels. Enter product namemake or model. Vessel material can also be an important factor. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air.

Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask.

A hinged holder in the cover facilitates handling of the test flask.

For such materials, ignition is dependent upon the thermal and kinetic properties of the decomposition, the mass of the sample, and the heat transfer characteristics of the system.

Within certain limitations, this test method can also be used to determine the autoignition temperature of solid chemicals which readily melt and vaporize at temperatures below the test temperature and for chemicals that are gaseous at atmospheric pressure and temperature.

Lab Equipment for Sale: Adjustable mirror permits safe viewing of the flask interior during testing. These temperatures can be expected to vary with the ast, pressure and oxygen concentration.
